Creates a new plot definition for plot number
n
.
type
specifies the type of the graph plot.
1 = scatter plot
2 = xyline plot
3 = box plot
4 = histogram
5 = modified box plot
mark
specifies the display type of the mark.
1 = è(box)
2 = × (cross)
3 = + (plus )
4 = é(square)
5 = ø(dot)
bucketSize
is the width of each histogram
“bucket” (
type
= 4), and will vary based on the
window variables xmin and xmax.
bucketSize
must
be >0. Default = 1.
Note:
n
can be 1–9. Lists must be variable names
or c1–c99 (columns in the last data variable
shown in the Data/Matrix Editor), except for
includeCatList
, which does not have to be a
variable name and cannot be c1–c99.

NewProb CATALOG
NewProb
Performs a variety of operations that let you
begin a new problem from a cleared state
without resetting the memory.
• Clears all single-character variable names
(Clear a–z) in the current folder, unless the
variables are locked or archived.
• Turns off all functions and stat plots (FnOff
and PlotsOff) in the current graphing mode.
• Perfoms ClrDraw, ClrErr, ClrGraph,
ClrHome, ClrIO, and ClrTable.

expression
If the integrand
expression1
contains no variable
other than
var
, and if
lower
and
upper
are
constants, positive ˆ, or negative ˆ, then nInt()
returns an approximation of ‰(
expression1
,
var
,
lower
,
upper
). This approximation is a weighted
average of some sample values of the integrand
in the interval
lower<var<upper
.

The goal is six significant digits. The adaptive
algorithm terminates when it seems likely that
the goal has been achieved, or when it seems
unlikely that additional samples will yield a
worthwhile improvement.
A warning is displayed (“Questionable
accuracy”) when it seems that the goal has not
been achieved.
